INSULA'IOR.

Application filed April 6, 1921. Serial No. 458,941.

To all whom it may concern:

Be it known that I, JAMES LEsLIE WILSON, a citizen of the United States,and a resident of Davenport, in the county of Scott and State of Iowa,have invented a new and Improved Insulator, of which the following is afull, clear, and exact description.

This invention relates 'to electrical supporting insulators forcurrent-carrying wlres. An object of the invention is to provide aninsulator to which the-wires or devices to be su ported can be veryquickly, simply and e ciently attached without the wire or su porteddevice coming in contact with metal or conducting material on theinsulator.

Another object resides in the provision of means whereby in its assagethrough the insulator the wire or evice can swing or have a curvedpassage without being subject to wear or friction.

A further ob'ect resides in the provision of means whereby the wire isheld firmly in place by a cover portion which can bevery quickly andeasily applied to and removed from the body portion of the insulator.

A still further object resides in the particular construction andarrangement of parts which are hereinafter described ind claimed andshown in the accompanying "drawin s.

The lIlVBIltlOll is illustrated in the draw ings, of whichigure 1 is aview of the insulator with the central portion in sections;

Figure 2. is a side elevation thereof;

Figure 3 is a top plan view of the body portion of the insulator withthe wire'or conductor shown in place; and

Figure 4 is an inverted plan view of the cover portion of the insulator.

The preferred embodiment of my invention, as shown in the drawings,comprises an insulator'having a body ortion 1 and a cover or top portion2 whic is adapted to be applied to the body portion 1. The cover andbody portions are adapted to meet in a' flat contacting surface suc as3. On the upper surface of the body portion 1 are provided a pair ofspaced cpro ecting ribs 4 and 5 which project upwar ly from the surfaceof the body portion 1 and extend across this surface between Oppositeedges. The

outer edges 6 of the ribs are straight, whereasthe inner adjacent edges7 are symmetrically curved as shown in Fig. 3. These ribs form betweenthem a recess in which a wire or conductor such as 8 is adapted to lie.By having the adjacent edges or surfaces 9 curved, it will be observedthat the wire 8 can swing in the recess formed between the ribs 4 and 5or pass therethrough in acurved manner without meeting any sharp edges,wear or friction. The lower surface or face of the cover portion 2 isprovided with a recess 9 of a depth equal to the height of the ribs 4and 5, and a width substantially equal to the width between the outeredges 6 of the ribs 4 and 5. This recess is provided with lateral walls10 which are adapted to lie closely adjacent of the ribs when the coveris placed on top of the body portion 1.

In a line at right angles to the line of extension of the recess 9,through the cover portion 2 and on opposite sides thereof, are disposeda pair of projecting lugs 11 to which suitable latch members 12 arepiv-.

oted. These latch members 12 are made of wire bent over in the formshown to engage with lugs 11 and at the other end provided with anunder-turned loop portion 13 which is adapted to engage under the loweredge of a shoulder 14 on the body portion. This shoulder 14 is in theform of an outwardly projecting flange portion extending circularlycompletely around the body portion.

In the application of the device, the cover portion is supposed to beremoved from the body portion; whereu on the conductor or wire 8 isplaced in posltion. The cover portion is then placed on the body portionwith the recess 9 disposed over and embracing the ribs 4 and 5 and,therefore, confining the wire in the grooves between the ribs 4 and 5.The latch members 12 are can ht under the edges of the flange or shouler 14, and b 1 reason of the resiliency of each wire latc member 12, thecover is held firmly on to the body portion.

What I claim is':

An insulator, comprisin a body havin at the upper end an annu arshoulderan provided on its upper face with spaced ribs of a height alittle greater than the diamwhereby it is not subjected to i the edgesor surfaces 6 Y v a recess of A the ribs, said recess extending entirelyeter of the wire te beheld therehetween,

a depth equal to the height of across the face of the cover and havingamen-7e straight Walls ,outer edges of t pivoteqi to oppesite engaging;the shoulder? .the cdver on 1 ing close to the straight e ribs, andlatch'members' sidespfthe cover and 1 i'he bedyi191 lock the body withtheir faces (iireetl'y incontact with each other.
